I still use jacketed in some cases but I mostly use cast. I cast my own and have a number of moulds. It can be another hobby in itself.

You will read of references to SWC style bullets - this style of bullet was made famous by Elmer Keith. They work fine in revolvers but the sharp edges can hang up in lever guns and generally the nose is too long to cycle in a lever gun when the bullet is seated to the crimp groove. It’s best to used RNFP or truncated cone styles in leverguns. They feed really well. If the alloy used is not going to expand then improved killing effect can be had by using a bullet with a wide meplat, but if it’s too wide it may not cycle well. There has been a resurgence of interest in HP moulds in recent years and a few makers now offer interesting HP designs. Casting your own offers a lot of different options as you can tailor the bullet style, weight and alloy to the application.
